A Secure and Improved Safety Message Collection with Increased Privacy-Preserving Algorithm for VANETs

Vehicular Ad hoc NETworks (VANETs) are going to help in deploying Intelligent Transportation Systems (ITS). Various schemes proposed in the literature use vehicles equipped with On Board Units (OBUs) to collect events such as weather conditions, collision prevention, and many others to notify drivers about these events. However, several existing schemes don't consider safety message collection in areas with a low density of vehicles. These areas also could have bad road conditions (e.g., icy roads) and may have poor connectivity. Therefore, in this paper, we improve safety message collection and notify the drivers about these incidents in advance, so they can take proper actions. In addition, the security and privacy of vehicles are achieved. We also improve the privacy-preserving of vehicles.
